Paint roller spinning and cleaning device



A` 14, 1959 H. A. JOHNSON PAINT- ROLLER SPINNING AND CLEANING DEVICE Filed Jan. 20, 1958 K. L m o mi om mw. h1 I v w. w Y HAB United States Patent() PAINT ROLLER SPINNING CLEANING DEVICE The present invention relates to a simple, practical and highly eicient device through the medium of which a user thereof may mechanically support a conventional type paint roller for purposes of spinning, cleaning and drying the same.

Persons conversant with the state of the art to which this invention relates are aware that many and varied styles and forms of supporting and spinning devices for paint rollers have been devised and proposed for adoption and use. Not many of these prior art adaptations have, apparently, met with widespread endorsement and use. Therefore, it is an object of the instant concept to structurally and otherwise improve upon the efforts of others working in this line of endeavor.

A mere glance at the views of the drawing will reveal that the embodiment of the invention herein disclosed does not need or rely upon an electric motor or power driven shaft. Instead, a simple hand rotated shaft is employed to drive a gear and pinion, the pinion carrying the driven shaft and being provided on its motion transmitting end with a clutch-like head or an equivalent adapter having friction driving association to the end of the paint roller and enabling the user to impart the quick start necessary for successful cleaning, by centrifugal action, the jacket on a paint roller.

Another object has to do with the construction which is of the utmost simplicity in construction, is inexpensive enough to be purchased for use by the average homeowner and is practically self-cleaning inasmuch as the splash hood or shield, which is utilized, cleans itself while the device is permitting the cleaning solution to drip and gravitate from the interior surfaces of the shield back down into the paint pan.

The invention is also such that the paint roller or jacket does not have to be dismantled and this, obviously, eliminates a messy and time-consuming aspect of the over-all job. In addition the bottom edges of the side walls of the hood or shield are so constructed that they attach directly to the upstanding walls of the pan, obviating the use of any other containers for the cleaning iuid. This means that when one is through with the cleaning job the entire mess, so to speak, has been accumulated in the paint pan, right where the job started. Also the construction lends itself to the appropriation and use of shields which may be made in desired sizes to accommodate rollers of various sizes.

The invention also features a simple arrangement of gearing in a housing properly constructed and attendant components so that by employing the hand operated gearing the roller can be spun in both directions. This is a valuable aid in that when the roller is spinning in one direction then suddenly reversed the nap on the jacket is raised and consequently the roller is more readily cleaned and dried.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the views:

Fig. 1 is a view showing the pan in section, the attachable device primarily in elevation with portions broken away and shownin section and `illustrating its construction and mode of use.

Fig. 2 is an end view observing Fig. 1 in a direction from right to left with portions appearing in section.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.

Fig. 4 is an enlarged fragmentary view showing the construction with parts in section and elevation and emphasizing the peculiar construction of the adapter.

Fig.'5 is a view similar to Fig. 4 showing a modified adapter.

Fig. 6 is a perspective view of the modified adapter by itself.

With reference to Figs. 1 to 4 inclusive and particularly to Fig. 1 the paint pan is denoted by the numeral 8 and has a at horizontal bottom 10, and upstanding vertical marginal walls 12 having outstanding lips or beads 14 at the top. The lower edge portions 16 of the vertical side walls 18 have selectively usable and properly paired bayonet-type keeper notches or slots 20, 21 and 22 which serve to detachably mount the substantially inverted U- shaped hood or shield 24 on the walls of the pan with the edges 16 practically lowered into the receptacle portion and therefore serving to nicely drain the cleaning solution back into the pan where it is trapped and readily disposed of when the spinning and cleaning job is over. The bayonet slots 20 and 21 and the bayonet slots 22 extend in opposite directions (see Figure l) and the beads 14 on the end walls of the pan 8 are snapped thereinto. As already stated the hood is substantially U-shaped and the bight portion 26 spans the pan in the manner as best shown in Fig. 2. The open ended slot 28 at the left in Fig. 1 serves to accommodate the wire or rod frame of the paint roller. The roller is denoted generally by the numeral 30 and is conventional, being tubular and mounted on the spindle or shaft 32 forming a part of the frame. The intermediate portion 34 of the frame slips removably into the slot where it is properly supported. The handgrip 36 is disposed on the exterior of the hood. With reference to Fig. 4 the substantially cup-shaped or recessed end portion or closure 38 which is used on most conventional type paint rollers has the threaded end portion 40 of the shaft 32 extending therethrough, said end portion 40 having threaded thereon a thumb nut 42. To provide the desired friction clutch drive the adapter head or member 44 is provided with a recess 46 so that the head becomes a sort of a cup to accommodate the portions 40 and 42. The leading end of the head is convex at 48 and fits nicely into the portion 38. The adapter head has a neck 50 to receive the screw threaded end 52 of the driven shaft 54. The connection is made by way of an assembling nut 56. The outer end of the driven shaft is journaled in an appropriate bearing 58 on the upper portion of the gear box or housing 60 which is provided with ears 62 bolted or otherwise connected to the short vertical end wall or plate 64 of the shield. The driven shaft carries a pinion 66 (Fig. 2) which is driven by a gear 68 which is in turn mounted on the driveshaft 70 turnable in a bearing 72 and operated by the hand crank 74.

Where the type of roller is that shown in Fig. 5 at 76 and a substantially disk-like end wall 78 is provided one has to provide, by punching or otherwise two holes 80 in the end wall. These serve to accommodate the prongs or fingers 82 on the U-shaped adapter 84 carrying a collar 86 attached to the driven shaft 88.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous mans-aa modifications and, changes; WilL neadily oceurA to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly al1 suitable modifications and equivalents may' be. resorted; to, falling within the scope ofthek invention as'` claimed.V

What is claimed* as new is aslfollowsl:

Ay centrifugal cleaner forpaint applicators: of the type including a shaft, a tubulai roller comprising a substantially cup-shaped end closure. journaled on.. one end portion of the shaft and a retaining mit threaded on said one end portion of said shaft and engagingv said end closure, said cleaner comprisingr apan, an inverted, generally VU-shaped shield mounted: on saidv pan and open at one end for the reception` oitheY roller and the shaft,

plate on theI other endA of the shield, aV shaft rotatably mounted on said plate, a clutch member on the second named shaft frictionally engageable in the end closure for operatively connecting said second named shaft to the roller, said clutch member being substantially cupshaped for accommodating said one end portion of the first named shaft and the nut, and means for actuating the second nam-ed shaftu fon spinning` the nullen.
